METAL-BED FASTENING.

Specification of Letters Patent.

Patented Jan. 16, 1917.

Application led February 23, 1912. Serial No. 679,524.

To all whom it may concern:

Be it known that I, WILLIAM T. BONNER, a citizen of the United States, residing at San Francisco, county of San Francisco, State of California, have invented a new and useful method of attaching the horizontal metal members (5) of metal beds to the supporting vertical members (3) Comprising the head and foot ends of metal beds, consisting of a hook,V (2,) alongitudinal slot (l) in vthe vertical support, (3,) a shoulder (Il) to hold the vertical members (3) rigid. v

In the drawings, Figure 1 is a perspective view of the post and fastening. Fig. 2 is a horizontal sectional view of the post and fastening connected. Fig. 3 is a side elevation of the fastening detached.

The -form of the shoulder is approximately cylindrical with a segment out out so that its cross section is approximately a crescent with slightly rounded horns. The hook 2 is so set between the bearing edges of the shoulder that when the hook isenga ged in the slot of the standard, or vertical support, and pressed home, the edges of the shoulder impinge upon and fit closely to the standard. The peculiar form of the and the relative position to it of the hook, 'permits it to fit exactly either or l Wrought pipe or 2 brass covered steel tubing, (which are the'sizes of pipe most in commercial use in the `manufacture of metal bed posts or standards) or, with a,

slight tting with a file the fastening may be made to fit any size of pipel or standard; The Web to which the'horizontal members of the bed are attached is of new and peculiar form, reinforced in the angle whereattached to the shoulder, and so attached,2 and of suoli form that the entire weight perimposed and not', as is usual, with a shearing strain upon connecting bolts.

The action is described as follows: The fastening is secured to the horizontal members of the bed with bolts or rivets 'and the hook inserted in the slot of the standard,

G Lwii" bed, frame and springs, may be carried su-Y a powerful clamping effect permitting no side lash or movement whatever even though the hook fits loosely against the sides of the longitudinal slot; further the hook brings the entire length of the shoulder edges (both above and below the hook), tightly against the standard and the shoulder then acts as a' reinforcement to the standard,besides resisting the strains tending to cant the standard forward or backward.

The form of the shoulder is such that it is obvious that,-Whatever the size of the metal standard the fastening will make a neat and sightly connection.

I do not limit myself to the precise form shown as it is obvious the parts may be varied in length and slightly in the shape of the cross section Without changing the intent and scope of the improved fastening.

I claim:

l. In combination with a hollow metal bed post, having, a vertical slot and a side rail, a vertical member connected to the side rail and having two opposed relatively long continuous vertical bearing edges which are adapted to engage the periphery of the bed post throughout their lengths and at two spaced points, and directlyv at the front face or portion of the bed post whereby the member' vcan be applied to posts of varying diameters and regardless of the diameter Will still engage the front face of the post, and a hook connected to the member and adapted to engage in the slot of the bed post to draw. said spaced vertical edges against the periphery of the bed post.

2. In combination with a hollow metal bed post having a vertical slot and va side rail, a member connected to said side rail "having" im outwardly inclined hook ccnarranged vertically and the radius of curva- .ture of said shoulder on the side ,toward the bed post being less than the radius of curvature ofthe post whereby the shoulder .contacts with the post only at its ends along two vertical lines and whereby the shoulder is adapted to cooperate with posts of different diameters.

:3. ln combination with a hollow metal hed post having a 'vertical slot, of a member l'or connection to said side rail having an outwardly inclined hook united therewith adapted to draw the member and the bed post together forcibly When the hook is fori-od against the lower edge of said slot, .said member having a crescent shaped shoulder thereon, Said shoulder having arms with rounded ends projecting toward and conlacting with the front outer face only of the lied post, the distance between the lines of contact of said arm with the post being materially less than the diameter of the post and said shoulder extending above the hook,

the distance between the throat of the hook and the top of the bearing being greater Y than the length of the hook.

4. As an article of manufacture, a member for connecting the hollow metal bed post With a side rail of a bed, said member comprising in combination an outwardly inclined hook, a crescent shaped portion rigid with said hook having rounded ends for engaging with the front outer face of the bed post, .said crescent shaped shoulder extendingabove the throat of the hook a distance greater than the length of the hook.

Certicate of Correction.

It is hereby certified that in Letters Patent No. 1,212 736, granted January 16, 1917, upon the application of William T. Bonner, of an Francisco, California, for an improvement in Metal Bed l*`ast,enings, an error appears requiring correction as follows: In the drawing.r insert the word and numeral Fig. 1, and Figures 2 and 3 should appear as shown below as part of the Letters Patent and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the case in the Patent Oce.
